Will I still need to submit paper documents?

  • If you have successfully filed the corporate income tax return online, do not send any paper copy to TRA.  Your online confirmation number is the proof that TRA has already received your return.
  • If you include an Alberta Scientific Research and Experimental Development (SR&ED) Tax Credit - Schedule 9 in the net filed Alberta corporate income tax return package, the corporation will not be required to file the corresponding "Listing of SR&ED Projects Claimed in Alberta" (AT4960). However, during a review or audit of the return, TRA staff may request you to provide the completed "Listing of SR&ED Projects Claimed in Alberta" in paper format.
